Stress is one of the main causes in determining insomnia.
It usually resolves once the initial event subsides.
For some individuals, perhaps those more vulnerable to sleep disturbances, insomnia may persist long after the initial event, possibly because of conditioning factors and heightened arousal.
Happy occasions such as getting married, promoted, or going on a vacation can cause stress reaction, not only because because participation in the event is occurring but also in the preparation.
More obvious events that occur throughout one's life are the loss of a job, a loved one, or the need for surgery.
The development and course of insomnia as cataloged by the DSM-5 include: The onset of insomnia symptoms can occur at any time during life, but the first episode is more common during young adulthood.
Less frequently, insomnia begins in childhood or adolescence.In women, new-onset insomnia may occur during menopause and persist even after other symptoms, such as hot flashes, have resolved.Insomnia may have a late-life onset, which is often associated with the onset of other health-related conditions.Insomnia can be situational, persistent, or recurrent.Situational or acute insomnia usually lasts a few days or a few weeks and is often associated with life events or rapid changes in sleep schedules or environment.Some 50 to 70 million Americans have a sleep or wakefulness disorder, according to the Centers for Disease Control and Prevention.Insomnia is not defined by the hours of sleep a person gets or how long it takes to fall asleep.Individuals vary in their need for and satisfaction with sleep.A feature of insomnia is that individuals experience distress or impairment in functioning as a result of their poor sleep.If the symptoms last three months or longer, the insomnia is said to be persistent.Insomnia is considered to be recurrent if two or more episodes occur within the space of one year.
